GEORGE lV. BUTLER, OF PALMYRA, CANADA.

AXLE-LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 615,801, dated December13, 1898.

Application filed January 22, 1896. Serial No. 576,474. (No model.)

To all whom it may concern: Be it known that I, GEORGE W. BUTLER, acitizen of the Dominion of Canada, residing at Palmyra; in the county ofKent and Province of Ontario, Canada, have invented new and usefulImprovements in Axle-Lubricators, of which the following is aspecification.

My invention relates to that class of axlelubricators which embrace alubricant-cup arranged upon the bar of an axle and having a tube.extending through the collar of the axle-spindle, so as to feedlubricant to a groove in said spindle.

The general object of the invention is to provide a lubricator whichembodies but a minimum number of parts, and is therefore susceptible ofbeing cheaply produced and is not likely to get out of order in use.

With the foregoing inview the invention will be fully understood fromthe following description and claim, when taken in conjunction with theannexed drawings, in which Figure 1 is a perspective view, partly brokenaway, illustrating one end of an axle equipped with my improvements.Fig. 2 is a longitudinal central'section offthe same. Figs. 3 and 4 aretransverse sections taken in the planes indicated by the broken lines 33 and 4 4, respectively, of Fig. 2.

In the said drawin gs similar letters desig- 'nate corresponding partsin all of the several vlews.

The axle bar A supports the ordinary wooden bolster-bar B, to which itis suitably connected,and has the usual spindle a and collar b, thespindle being provided with a longitudinal groove c and the collar withan aperture d, connected with the groove, as shown. On the axle-bar atone end of the bolster-bar is arranged my improved oil-cup C, which ispreferably cast or otherwise formed in one piece. This cup has a nipplec arranged in the aperture CZ of collar h, so as to feed lubricant tothe groove in the spindle a, and it is also provided at its inner endwith the extended horizontal and vertical wallsfg,which are designed toreceive between them the reduced end of the bolster-bar, to which thecup is connected by screws h, taking through the 5o walls g, as bestshown in Fig. 4.

The entire upper side of the cup C is arranged in the samevhorizontalplane as the upper surface of the'wall f in order to afford a iiat seatfor a cover D, which has for its purpose to tightly close the cup, andthereby exclude grit, dust, dac., from the interior thereof. The cover Dis of a shape and size to entirely rest over the top of the cup and theextended wall f thereof, and it is provided 6o in its inner end with abifurcation c', and is also provided with a bar j, bridging thebifurcation, the said bar being arranged about the distance shown fromthe inner end of the cover, for a purpose which will presently appear.

E is a spring which in addition to connecti ing the cover D with thebolster-bar B serves to yieldingly press the cover against the cup toeffectually exclude foreign matter from the 7o interior of said cup, andYyet permits of the coyer being conveniently raised when it is necessaryto charge thev cup with lubricant. The spring is connected at one end tothe up per side of the bolster-bar B and is provided at its opposite endwith a barrel or eye 7c, which loosely receives the bar j of the coverD. By virtue of this construction the cover E has a movement independentof the spring, which enables it to always iit tight upon and 8o securelyclose the cup. While this is so, the bar j being arranged at a distancefrom the inner end of the cover E prevents the outer end of the coverfrom rising except when it is pulled up with the spring.

It will be appreciated from the foregoing that my improved lubricatorembodies but a minimum number of parts, which are not likely to get outof order in use, and that it is adapted to be quickly and easily secured9e in its operative position on an axle.

Having thus described my invention,\vl1at I claim is- The combination ofan axle having a lon gitudinally-grooved spindle and a collar pro- 9 5vided with an aperture coincident with the groove of the spindle, abolster-bar secured on the axle-bar and having its outer end reduced,the lubricant-cup arranged 0n the per side of the bolster-bar and havingan eye axle-bar and having J[he nipple arranged in receiving the bar ofthe'cover, substantially Jche aperture of the Collar and also having theas specified. flat upper side and the flat horizontal Wallf Dated atRidgetown this 12th day of July,
